I can see 2 possible options for this happening, maybe the filesystem is for some reason shared as read-only in which case the nfs-server on the core needs to be reconfigured. Or the filesystem is mounted read only during the boot of the diskless machine, in this case you could try logging in as root (should have no password) and run these commands:

mount / -o remount,rwstartxWith a bit of luck I reckon that will remount the root filestem as read-write, and start the graphic environment. If this works (at least the first command) then the bootparameters of the diskless' kernel probably need to be readjusted.

also you can post the output of cat /etc/fstab or mount to see if there are rw options. also, post the output of startx too see for any error messages. it is possible that the xorg.conf might be incorrect.

maybe it could be helpful to force the mounting as rw of the diskless md. you should put just for a test the option rw into this line:192.168.0.2:/usr/pluto/diskless/113 / nfs initr,udp,rsize=32768,wsize=32768,retrans=10,timeo=50 1 1it should be after the miodification:192.168.0.2:/usr/pluto/diskless/113 / nfs initr,udp,rw,rsize=32768,wsize=32768,retrans=10,timeo=50 1 1

Ah the infamous single network card setup rears it's ugly head again. Try to at least give the physical and virtual adapter eth0 and eth0:0) different ip-addresses. And that's about all the help I can give you with that kind of setup.
